In this week’s lectionary reading from the Hebrew scriptures, Moses confronts the Israelites with a stark reality: “I have set before you today life and prosperity, death and adversity.” In other words, if we “obey the commandments of the Lord your God” then the life we choose will be full of blessings -- a state of affairs that the psalmist underlines by pointing out that those who “walk in the law of the Lord” will find great happiness.
